Product Details

Overview & Technology

The Keeper 785 blends proven materials and practical design to give commuters and road riders dependable security without excessive weight. The chain uses 7mm four-sided links forged from 3T manganese steel, a high-strength alloy that resists cutting and deformation better than standard carbon steel. The lock head features a high-security disc-style cylinder that is pick- and drill-resistant, paired with a hardened deadbolt and an end-link design that secures the chain directly to the locking mechanism. Inside the lock, Finish Line Dry Teflon Lube is pre-applied to reduce wear and protect components from corrosion for long-term reliability.

Key Features & Real-World Benefits

What you get on the road: a 85cm (33.5") chain that is long enough to wrap around a frame and a fixed object, with 7mm thickness that balances theft resistance and portability. The four-sided links make bolt croppers and pry tools less effective, while the hardened deadbolt resists leverage attacks where thieves try to force the link free. • Disc-style cylinder: pick and drill resistance adds real protection where opportunistic thieves target cylinders. • Pre-lubricated internals: Finish Line Dry Teflon Lube reduces friction and shields internals from moisture and grit. • Compact weight and size: At roughly 2.95 lb and 85cm length, the Keeper 785 is easy to carry or pack in a bag.

Fit & Compatibility

The Keeper 785 is a keyed chain lock designed for general bicycle security and fits most road and commuter frames. With an internal length of 85cm (2.8') you can typically loop it around the frame and rear wheel to a rack, signpost or sturdy street fixture. Note: this model ships without a mounting bracket, so plan to carry it in a bag, pack or use an aftermarket bracket or carrier if you prefer on-bike storage. Available colorways (Black, Red, Grey, Purple) and the integrated chain design suit both practical and aesthetic needs. The chain thickness and overall weight make it less suited for lightweight race setups where minimal mass is critical, but ideal for riders prioritizing everyday security.

Who It's For

The Keeper 785 is aimed at urban commuters, road riders who stop in town, and anyone who needs reliable mid-level security without a heavyweight chain. It's a great choice for riders who lock in low- to moderate-risk areas — bike parking lots, city streets for short errands, and campus or workplace racks. If you live in a high-theft area or need maximum resistance against heavy tools and prolonged attacks, consider upgrading to a thicker chain or a hardened U-lock rated for maximum security. For everyday city use, the Keeper 785 strikes a solid balance of protection, portability, and price.

Frequently Asked Questions

Is the Keeper 785 easy to carry on my bike?

The Keeper 785 does not include a mounting bracket, so most riders carry it in a pack, saddlebag or pannier. If you prefer on-bike mounting, compatible aftermarket chain brackets or strap systems are available to secure the lock to your frame.

How secure is a 7mm chain compared to other locks?

A 7mm manganese steel chain like the Keeper 785 offers solid mid-level security—stronger than thin cable locks and lighter than heavy-duty 10–12mm chains. It's effective against opportunistic theft and quick attacks but less resistant to prolonged attacks with power tools; for very high-risk areas choose a beefier chain or a high-security U-lock.

Does the lock come with keys and can I get replacements?

The Keeper 785 is a keyed lock and ships with keys. For key replacements, Kryptonite offers key services and replacement keys via serial number or proof of purchase—contact Forest Bikes or Kryptonite customer service with the product details and part number (000853) for assistance.

Is the cylinder really pick and drill resistant?

Yes. The Keeper 785 uses a disc-style cylinder engineered to resist common cylinder attacks like picking and drilling. While no lock is completely impervious, this design significantly raises the skill and time required for a thief to defeat the lock.

How should I maintain the lock to keep it working smoothly?

The internal components are pre-coated with Finish Line Dry Teflon Lube for durability, but periodic external cleaning is recommended. Wipe off dirt and moisture, avoid soaking the lock, and apply a lock-specific lubricant or graphite to the keyway occasionally to ensure smooth operation.

Can the Keeper 785 secure both wheels and frame?

At 85cm the chain can usually loop through a frame and one wheel when anchored to a fixed object. For securing both wheels and the frame simultaneously you may need a longer chain or an additional cable/U-lock depending on your bike's size and the rack configuration.

Buying Guide

When choosing a chain lock, balance security, length and weight. Look for hardened steel alloys (like 3T manganese), a protected cylinder design and a practical length that lets you lock frame and wheel to a fixed object. Thicker links increase cut resistance but add weight—decide whether portability or maximum security is your priority. For daily commuters and road riders, a mid-weight option like the Keeper 785 offers reliable protection for short stops in urban areas. If you frequently park in high-risk locations or need to secure multiple bikes, consider a heavier chain or pairing this lock with a secondary U-lock for greater coverage.
